2. Network Management and ISO Model
Performance management
Configuration Management

3. Objective Management User Satisfaction – application work correctly
Performance – response time
Availability - user satisfaction
Reliability – performance of operation at a given period
Backup – safety of information
Network uptime – restoration of service
Information Availability – open line communication
Cost effectiveness – meaningful solution to the problem
Prior planning - network future plans
Modular Expansion – Future expansions
Relocation of equipment – a more strategic approach to satisfy clients

4. Formula Availability
Availability = MTBF
MTBF+MTTR

10. MTTRepair = MTTDiagnose + MTTRespond + MTTFix
Failure Statistics
Mean time between failures (MTBF)
Number of hours or days of continuous operation
Indicates the reliability of a component
Mean time to repair (MTTR)
Average number of minutes or hours until the failed device is operational again
MTTRepair = MTTDiagnose + MTTRespond + MTTFix
Average number of minutes until the root cause is diagnosed (shows efficiency of NOC)
Average number of minutes until the service or vendor personnel arrives at location
Average number of minutes until problem is fixed (shows efficiency of repair people)
